Automated Heroku App Health Checks
Every night, WebRun opens the Heroku dashboard, checks each app you nominated for crashed or scaled-to-zero dynos, add-ons in a warning state, and recent error activity, queues a Twilio text to your on-call number when an app is actually down, and posts the full health rundown to Telegram so the morning starts with a known state.
How do I get alerted when one of my hosted apps goes down overnight?
WebRun checks your Heroku apps every night. It reviews dyno state, add-on health, and the latest release on each app, queues a Twilio text to your on-call number when something is genuinely down, and posts the full rundown to Telegram, so a failed app is known overnight instead of at 9am.
- A crashed app is escalated the same night
- Every app has a nightly recorded state
- On-call is only woken for something genuinely down

How is each run configured?
Secure by default
Connect once, stays signed in
WebRun signs in once and keeps each session in a persistent environment, so every run picks up right where it left off.
Every action is checked against this policy before it runs.
Questions, answered
Will it text customers or anyone outside my team?
No. The Twilio text goes only to the on-call numbers you save at setup. Any message addressed to a number outside that list is queued for a person to approve rather than sent.
Will it restart dynos or roll back a release?
No. WebRun reads the Heroku dashboard and does not scale, restart, deploy, or roll back anything. Recovery actions stay with the engineer who gets the alert.
What stops it waking on-call over nothing?
The text fires only when an app is genuinely down, meaning a crashed dyno, a dyno scaled to zero that should be running, or an add-on in a failed state. Everything else waits in the Telegram rundown.
